DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. Parts which are not directly related to the present invention are omitted for convenience of description, and the same or similar components are denoted by the same reference numerals throughout the specification.

1 is a block diagram of a configuration of a broadcast receiver 1 according to the present invention. 1, a broadcast receiver according to the present invention may include a receiving unit 120, a signal processing unit 110, a storage unit 130, a first interface unit 140, and a control unit 100.

The broadcast receiver 1 of the present invention includes a receiver 120 for receiving broadcast signals of a plurality of channels, a signal processor 110 for processing a broadcast signal, a storage 130 for storing information on broadcast signals, A first interface unit 140 for transmitting the broadcast signal to the display device 200, a display unit 200 for displaying the broadcast signal on the basis of the program guide for the broadcast signal, And a control unit 100 for controlling the generated setting information to be transmitted together with the processed broadcast signal.

The receiving unit 120 may receive broadcast signals of a plurality of channels provided by a broadcasting signal provider such as a cable operator. The receiving unit 120 may receive an encoded broadcast signal provided by the broadcast signal provider, and a signal including a program guide having information such as schedule, schedule, etc. of the broadcast program may be received together with the broadcast signal . The control unit 100 transmits the broadcast signal, that is, the video and audio signal, to the signal processing unit 110 and the program guide, which is information related to the broadcast signal received together with the broadcast signal.

The signal processing unit 110 may process a plurality of received broadcast signals under the control of the control unit 100 and output the signal to the display device 200. The signal processing unit 110 may be a decoder for decoding a video signal and a voice signal of a broadcast signal. The signal processing unit 110 may include program logic for adjusting a broadcast signal, or may transmit setting information to the display device 200 in addition to a broadcast signal. The signal processing unit 110 encodes a signal into a digital code and stores it in a form of a digital signal. When the signal is encoded or decoded, the coded signal is encoded into a original signal. The video signal and the audio signal are decoded in the original form The video signal and the audio signal can be changed by applying the program logic under the control of the control unit 100 and the setting information for controlling the broadcasting type of the display device 200 can be processed. For example, the signal processing unit 110 may process a command control signal for controlling the image type of the movie image type according to the channel change to the movie channel of the display device 200 under the control of the control unit 100.

6 is a schematic diagram illustrating operations between a broadcast receiver 1 and a display device 200 according to an embodiment of the present invention.

The broadcast receiver 1 receives a broadcast signal including EPG data and updates EPG data stored in the storage unit 130 of the broadcast receiver 1 continuously. Upon receipt of an input signal for a channel change by the user, the EPG data is searched and the image type of the corresponding channel of the change input is grasped to generate setting information. The generated setting information is transmitted to the image control unit 210 of the display device 200 through the CEC pin of the HDMI cable together with the broadcast signal. Accordingly, the image control unit 210 of the display device 200 can control the image type of the channel selected by the user by adjusting the image.

Fig. 6 illustrates an actual case by way of example.

When the power of the broadcast receiver 1 is turned on, a broadcast stream including a program guide is input from a broadcast signal provider. In the present invention, the term program guide refers to information included in EPG contents and information obtained from EPG contents.

The program guide included in the broadcast stream may include various types of sports programs (e.g., baseball, football, football), movie programs (e.g., horror, action, science fiction, melodrama, Programs (eg, rock, classical, dance, etc.), documentary programs, and news.

The program guide is stored in the storage unit 130. Then, the latest program guide included in the broadcast stream is updated. Thereafter, the user selects a channel, and the control unit 100 of the broadcast receiver 1 detects the channel change through the CEC of the HDMI cable connected to the display device 200. The control unit 100 searches for the program guide stored in the storage unit 130.

The program guide may include information such as title, brief description, date, time, channel number, detailed description, rating indicators, rebroadcast information, and the like. Also, the list may be organized by broadcasting type, channel, time, region, and the like. Program guides can be parsed to determine different programs for different types of programs that viewers can view (e.g., baseball, war movies, music programs, documentaries, news, etc.). In the updated program guide updated by the current user, the current program guide of the channel changed to the current condition such as date, time, and channel is found, and the broadcast type is identified using the information of the current broadcast program . If the identified broadcast type of the changed broadcast program is a war movie in the movie program, the control unit 100 generates setting information for the war movie.

The setting information may be a control signal for executing a control function for optimizing effects of a kind of video and audio such as an audio control mixer (not shown) of an audio amplifier (not shown). For example, suppose you are watching a soccer program on a sports channel. The most important feature is that the soccer players dynamically move on the green grass. In order to transmit the information to the user in realistic manner, the condition of the image and the condition of the voice are needed. The brightness of the second display unit 240 of the display device 200 may be adjusted to produce an optimal image and the contrast of the second display unit 240 may be adjusted to produce an optimal image. In addition, the control of the voice is likewise suitable for the soccer program such as the voice-oriented and the surround effect among the optimum conditions of the sound, so that the user can view the realistic soccer program. The display device 200 is provided with a menu for controlling video and audio for each broadcast type. The setting information generated in the broadcasting receiver 1 is transmitted to the display device 200 and the user directly controls the broadcasting controller 200 in the video controller 210 so as to automatically set the broadcasting type . ≪ / RTI >

Here, the display device 200 has settings for video and audio for each broadcast type. In addition, the user can manually change the setting to the condition of the video and audio preferred by himself / herself. For example, the equalizer of the audio (not shown) and the amplifier (not shown) includes setting information for the type of music by genre. For example, when the rock type is selected, the sound effect for the predetermined type of rock is increased by increasing the low sound level, lowering the middle sound level, and increasing the high frequency sound level by the sound level, To set the lock type. By doing so, listeners who prefer rock music can enjoy rock music, which is much more satisfying than what is heard in the regular type. Although an audio and amplifier equalizer has been taken as an example here, this is intended to aid understanding of adjusting the broadcast type of the present invention, for example, and will not be limited to the above-described embodiment.

In this way, even if the program for the recent broadcast program is continuously updated to change the channel during the viewing by the user, the broadcasting type of the display device 200 is adjusted to the broadcast type for the changed channel, It is possible to realize realistic viewing with the broadcasting type suitable for the corresponding broadcasting program.
